Tempe is considering replacing its fleet of gasoline powered cars with electric cars. The manufacturer of the electric cars claims a significant cost savings over the life of the fleet if Tempe chooses to pursue the conversion. If the manufacturer is correct, the city will save about $1.5 million. However, some critics argue that the technology is faulty and will result in significantly higher costs - estimated at a loss of $700,000 over the life of the fleet compared to gasoline-powered cars. A third possibility, suggested by independent analysis of an engineering firm last year is that the conversion will breakeven. A consultant hired by the city to assess the conversion program estimates the probabilities of the three outcomes - savings, loss, breakeven - at 30%, 30%, 40%, respectively.

The city has the opportunity to implement a pilot program that involves renting a small number of electric cars for three months and running them under typical conditions. This program would cost the city $75,000. The city's consultant believes the pilot program results will be useful for estimating the value of the conversion, but not conclusive. She has prepared the following table of probabilities based on the experience of other cities after 3- months of usage. For example, given that a conversion actually results in savings of $1.5 million, the conditional probabilities that the pilot will indicate that the city saves money, loses money, and breaks even are 60%, 10%, 30%, respectively.

Indication of outcome from pilot program	Actual outcome over the life of the fleet
Savings	Loss	Breakeven
Indicates savings	60%	10%	40%
Indicates loss	10%	40%	20%
Indicates breakeven	30%	50%	40%

Question: What is the expected value of information (EVI) under the assumptions of part (c)? Justify your answer using results generated by PrecisionTree (i.e., explain how you arrived at your answer from information in your decision tree).

(((Part c: Does your recommended strategy from part (a) change if the city is risk averse with a risk toleranceparameter of $1 million (with an exponential utility function)? Express the optimal strategy verbally and state the corresponding optimal expected payoff and the certainty equivalent.

Part a: Assuming the city wishes to use expected payoff as the criterion for decision making, use PrecisionTree to construct and solve a neatly labeled decision tree for Tempe's decision problem. Express the optimal strategy verbally and state the corresponding optimal expected payoff.)))
